CHARLES EDWARD l-IARING, OF NEW YORK, N. Y.

WINDOW LIFT.

SPECIFICATION forming part of Letters Patent No. 737,402, dated. August 25, 1903.

v Application filed April 3, 1903. Serial No. 150,988. (No model.)

To aZZ whom it may concern:

Be itknown that 1, CHARLES EDWARD HAR- ING, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful WVindow-Lift, of which the following is a specification.

This invention relates to windows, and has for its object to provide simple and inexpensive means to raise and lower the upper sash thereof.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of a window with my invention applied thereto, a part of the casing being broken away to show details of construction. Fig. 2 is a transverse view on the line 2 2 of Fig.1, and Fig. 3 is a detail view on an enlarged scale.

In the accompanying drawings like numerals of reference refer to the same parts in each of the views, and in the practice of my invention 1 provide a window, as 5, with an upper sash 6 and lower sash 7, with a lift of the following construction: A clamp 8, comprising a collar 9 and screw 10, is secured to each sash-weight 11, and the free end of the screw or shaft 10 is provided with a handle or knob 12, by means of which the weights are raised or lowered in order to lower or raise the upper sash.

In providing a window with my invention I prefer to provide each casing with a recess 13, having a rear wall 14 with a longitudinal slot 15, in which slides the shank of the screw or shaft 10. I also prefer to provide a slideplate 16, which I mount on the screw or shaft 10 adjacent to the knob 12 and which is preferably provided with lugs 17, adapted to fit in the slot 15 to act as guides for the plate 16. Each recess 13 is preferably closed by a panel-door 18, let into the casing of the window. The screw 10 is preferably proportioned in length, so that when the parts are in position the sash-cord 19 will be drawn slightly forward from the perpendicular, thereby tending to hold the plate 16 against the wall or partition 14 and the lugs 17 in the slot 15.

In operation the doors 18 are opened when it is desired to raise or lower the upper sash. A knob 12 is grasped in each hand, and by pulling upon the same the sash will be lowered, as the sash is kept in an elevated position by the weight, so that by elevating the weight the sash will be lowered. When it is desired to raise the sash, the knobs are pulled downward, thereby assisting the weights in their tendency to draw the sash upward.

The advantages of this invention will be readily apparent, as it is usually a very difficult matter to raise and lower the upper sash, and as a usual thing it is customary to raise the lower sash in order to get hold of the bottom of the upper sash to draw it down. Oftentimes this is very inconvenient, especially if there are curtains at the window. With my invention the upper sash is raised or lowered by simply opening the panel-doors and pulling up or down on the knobs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A window-1ift comprising a clamp secured to each weight of the upper sash, said clamp consisting of a collar surrounding the weight and a shaft passing through one side of said collar and bearing against the weight thereby forming a clamp with the opposite side of the collar, said shaft being prolonged through the casing, as and for the purpose set forth.

2. A windowlift comprising a clamp, a shaft forming part thereof and provided with a handle, a recess formed in the window-casing and having a longitudinal slot in the rear wall thereof through which said shaft passes, and means to hold said shaft in a substantially horizontal position, comprising a plate provided with lugs adapted to slide in said slot, said shaft passing through said plate, as and for the purpose set forth.

3. A window-lift comprising a clamp secured to the sash-weights,-a shaft forming part of said clamp and passing through a longitudinal slot in the wall of the casing, and a guide-plate mounted on said shaft and provided with lugs adapted to move in said slot, said shaft being provided with a handle, as and for the purpose set forth.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

CHARLES EDWARD IIARING.
